add tabs to existing project

Question

I have a running project with 2 xibs for 2 UIViewControllers (no storyboard). I am looking for the shortest way to add tabs at the bottom of the screen being able to switch between the views via the tabs.

Thanks,

Simon

SHORT ANSWER:

1. In your MainWindow add a UITabBarController
2. In your UITabBarController add UITabBarItem s for a UINavigationController
3. For each of those UINavigationController s set the RootViewController to be the UIViewController s that you have already

EDIT: More detailed steps, but not necessarily perfect:

1. Find out which view is loaded when your app is loaded (depending on your XCode, this may well be MainWindow.xib or its RootViewController )
2. Edit the thing from #1 (if defined in code, edit in code; if designed through XIB, edit through XIB) so that it is pointing to a UITabBarController (ie mainWindow.rootViewController = tabBarController in code)
3. Foreach view controller you want to add, add a UINavigationController . If you are using XIB, then just drag new navigation controllers to the tab bar. If you are using code, use tabBarController.viewControllers = @[navController1,navController2,navController3,...]
4. Foreach of the nav controllers you just created, set its rootViewController to be your ViewController you want to add.
